In this study, the available solar potential of some selected locations in Nigeria on an inclined, single-axis (considering 6 tracking orientations) and dual-axis tracking surfaces are assessed using hourly radiation data. More accurate and widely validated Perez anisotropic and Koronakis isotropic models are adopted in the estimation of the diffuse component of the radiation on an inclined surface before integrating trackers. The method utilized in the simulation are compared and verified by the result from System Advisor Model (SAM) before carrying out the detail resource assessment. The annual solar resource potential for the locations on a fixed surface inclined at an optimal angle ranges from 1621 to 2279 kW h m(-2), with the use of solar trackers; the yield would vary from 1664 to 2983 kW h m(-2). This amount of energy, if fully harnessed, would not only help in narrowing the gap between energy demand and supply but also would make a significant contribution in enriching the energy generation mix of the country. The increase in the annual energy yield of the dual-axis tracker compared to the other trackers and fixed tilted at optimal angle orientations ranged from 1.86% to 31.52%. Overall, the study is expected to provide a practical guide to aid designers and installers in the selection and implementation of suitable solar trackers in the country.

The effect of latitude on the performance of different solar trackers in Europe and Africa Bahrami, Arian; Okoye, Chiemeka Onyeka; Atikol, Ugur (2016-09-01) In this paper, the effect of latitude on the performance of different solar trackers is examined. The hourly solar radiation data of different locations around Europe and Africa measured on a horizontal surface is collected and utilized. Widely validated Perez anisotropic model is used to predict the diffuse component of the solar radiation on an inclined surface. Different solar trackers namely, Full/dual-axis, East-West (EW), North-South (NS), Inclined East-West (IEW), and Vertical-axis (V) trackers are c...
Evaluating the thermal stratification of Koycegiz Lake (SW Turkey) using in-situ and remote sensing observations Kurtulus, Tugba; Kurtulus, Bedri; Avsar, Ozgur; Avşar, Ulaş (Elsevier BV, 2019-10-01) The goal of this study is to evaluate the thermal properties of Koycegiz Lake using in-situ measurements and satellite based thermal infrared imagery. In-situ measurements of surface water temperature and water depth, as well as meteorological data, were used in the analysis. Images of the Landsat 8 TIRS (Thermal Infrared (IR) Sensors) at IR channels were taken from the data archives of United State Geological Survey (USGS), and were validated with surface in-situ measurements. Specific Electrical conductiv...
Testing the normality of the residuals of surface temperature data at VLBI/GPS co-located sites by goodness of fit tests TANIR KAYIKÇI, EMİNE; Sopaci, Eyup (2015-11-01) Evaluating the distribution patterns of surface temperature data at Very Long Baseline Interferometry (VLBI)/Global Positioning System (GPS) co-located sites w.r.t. normality is one of the most important issues in modeling surface temperature data over long periods. Such evaluation can generate algorithms for filling in missing data at measurement sites. Some algorithms in the literature, such as those in the study of Cho et al. J Coast Res 65. doi: 10. 2112/SI65-321. 1, (2013), require trend, harmonic, and...
Evaluation and Comparisons of the Models to Calculate Solar Irradiation on Inclined Solar Panels for Ankara Özden, Talat; Akınoğlu, Bülent Gültekin; Karaveli, Abdullah Buğrahan (2017-11-29) In the optimization and feasibility analysis of renewable energy systems, the accuracy of the simulation methods is extremely important. Thus, in the case of solar energy systems, estimating the monthly average daily solar irradiation incident on inclined solar panels is the main step of long-term feasibility analysis toward reaching the viable investments. In fact, most solar energy investor companies use silicon solar irradiation measuring instruments in Turkey although only a few of them also measure the...
Study on Q-RAM and Feasible Directions Based Methods for Resource Management in Phased Array Radar Systems Irci, Ayhan; Saranlı, Afşar; Baykal, Buyurman (2010-10-01) Our recent progress and results on optimal real-time resource allocation in phased array radar systems are reported. A previously proposed discrete resource allocation approach, the Quality of Service based Resource Allocation Model (Q-RAM), is analyzed and is observed to generate nonoptimal results. We identify the shortcomings of this method and first extend it using the Karush-Kuhn-Tucker (KKT) optimality conditions for the single resource type case. We obtain an algorithm that delivers a globally optima...
